My defence was that I fancied a bag, I queued for ages, and they were lovely! I wasn't going to swig them down with a strong can of drink (as was suggested) I didn't want the driver to lose his job just before Christmas (as was suggested) and oven chips wouldn't have fit the bill, (as was suggested)
The fact that I assured the driver I wasn't going to eat them on the bus meant that I really wasn't going to. (to those who thought I was lying to the driver "how did he know you weren't going to eat them?")
So, I'm unrepentant, and if I fancy another bag I shall attempt to take them on the bus again.
